  • This study investigates sediment transport at a very low-energy backbarrier beach in southern Portugal, from a spring-to-neap tide period, during fair-weather conditions. Rates and directions of transport were determined based on the application
  • evolution model, well validated over the study area. Tidal currents (mainly ebb velocities) were found to be the main causative forcing controlling sediment displacements. Transport rates were higher during spring tides, tending towards very small values
  • at neap tides. Results herein reported points towards the distinction between tracer advection and tracer dispersion in this type of environment. Tracer techniques allowed distinguishing the broad picture of transport, but revealed the need for refinement

  • . This study demonstrates that tides which peak around the bankfull level show reduced early ebb stage turbulence and flow velocity and encourage an extended depositional period. The dynamics of marshfull tides may be responsible for the maximum sediment

  • The AA. use a 9.3-year dataset of daily low-tide time exposure images from the double-barred beach at Surfers Paradise (Gold Coast, Australia) to analyse the temporal and spatial characteristics of morphological coupling within a double sandbar

  • evidence for abrasion, the AA. explore conditions in the geological past for tides that may have locally eroded bedrock.
